To end all the discussion about Moon being a distraction-or the man who drove the show to legendary status.
Let's look at it this way, Moon and Bonzo are etched onto people's minds as two of the best if not the best rock drummers ever. And both, appearing on the same stage, at the same time & even playing together, is a truly timeless moment in any way you put it, and even more so after both passed away.
Now whether you find Moon's comments funny or feel sorry for him, that's up to you, he'd pass away not long after this, so that could be an opinion changer, but to me IMHO, Moon's appearance & drunken spirit, actually adds to the wild party-esque jovial atmosphere of the show. See it for yourself.
